After six frustrating years of major injury setbacks since his memorable Test debut in Johannesburg in 2011, Cummins has ironically been Australia's fast bowling ironman this year while Mitchell Starc, Josh Hazlewood and James Pattinson have all been sidelined due to injury.

And unless the unfathomable scenario of another injury strikes in the next two months, the right-armer appears to be a walk-up start for the first Test against England in Brisbane, just his sixth Test and his first at home.

"More than anything, (I'm excited about) playing my first Test in Australia," Cummins said in Kolkata on Friday.

"I haven't really even been close to playing a Test in Australia so knowing in a couple of months that I could be playing at the Gabba in an Ashes Test, it'd be pretty crazy.

"I'm trying to get through this series and after that, all the focus will be on the Ashes and playing those first three Shield games.

The decision to send Cummins home early from India was always going to be a case of when and not if given his high workload over the past month and earlier this year.

Skipping the three-match T20 series next month allows him an extra two weeks of rest before NSW's first Shield game starts on October 26, one of three four-day contests before the first Test begins on November 23.

The move from Australia's selectors and coaching staff has the full backing of their star quick.

Cummins tears through Bangladesh top-order

"It's probably the only opportunity in a pretty busy schedule this summer to get a couple of weeks of rest," he said.

"I think if I stayed for the T20s, I'd only get around about a week before the Shield season kicks off. So it gives me just a bit of extra time to just prepare for red-ball cricket.

"Obviously, Bangladesh was a pretty tough tour so I think that gave us the final answer and it's seems like a pretty good decision, I think.

"You want to play every game for Australia that you can. But looking at the schedule it’s a good opportunity to really take a longer-term view and try and get ready for a big summer."
